I just ordered my Note 9. Samsung sent me a promotional email so I'll get $600 trade-in value for my S9+, plus $100 off from Verizon. That makes the Note 9 128Gb version $299 total after trade-in. Not too shabby. I loved the S-Pen on my old Note 3 so that's the main reason why I'm up(cross)-grading.
That makes for a nice deal. I would do it if I could get something like that. Enjoy
